Surveillance des risques d'effondrement dans l'après mine, besoins, méthodes

Abstract : At the time of the exploitation, the stability of the mining works mainly directed towards the safety of the minors and the safeguard of the mine, were practised with methods adapted to accessible and maintained buildings. Following the closing of the mines, these conditions not being more assured and the objectives of public safety resolutely tumed towards the safeguard the people and the goods on the surface, resuit in remotely seeking applicable total methods and from surface. Among those, we develop the typical example of the microsismicity which, before being applied to the monitoring of the risks of mining collapse had to answer a precise schedule of conditions to be qualified then validated. An example of its use successfully for the monitoring of the pillar of Nondkeil (Ottange, 57) is proposed.
